ABSTRACT
We describe the design of a speed-independent interface based on a pipeline token-ring architecture. The original goal was to build a reliable communication medium, able to tolerate up to two faults in any segment of the ring, to be used in an on-board multicomputer. We believe that the pipeline ring approach can help reduce some negative "analogue" effects inherent in asynchronous buses (including on-chip ones) by means of using only "point-to-point" interconnections. We briefly outline the major ideas of the channel's organisation, protocol and our syntax-driven implementation of the channel protocol controller. The protocol has been recently verified for deadlock-freedom and fairness.
